No. 54: Linus Garfield Linus

Charlie Brown (Talking to Lucy while Linus stands nearby): Halloween is over and the "Great Pumpkin" didn't show up again, did he?
(Linus is replaced by Garfield from Garfield)
Lucy: No, she didn't, didn't she?
(Linus reappears, looking embarrassed or maybe even horrified, as if he swapped dimensions with someone else for a couple of seconds)
Lucy: Never even occurred to you, did it?
